20A, up to 8S Lipo
The new iSDT K4 DUO charger is a powerful, compact, all-round charger. Thanks to the integrated power supply with 400W output, it can quickly charge with up to 400W at home via a 230V socket, which is distributed per port as required.
If the K4 DUO charger is supplied with DC voltage, for example from a battery or an external, more powerful power supply unit, up to 2x 600W output is possible! (min. 24V required!)
1-8s LiXX cells can be charged, with up to 800W possible in parallel mode. The extremely powerful balancer delivers up to 1.5A per cell, ensuring your batteries are optimally maintained and maximum performance is guaranteed.
The 2.8-inch IPS display is easy to read even in direct sunlight and simplifies operation. Operation is very intuitive and precise with the 3 buttons per charging output.
The USB-C port can be used for software updates and offers the function of charging a smartphone, for example, with 5V/2A.
Thanks to its compact design of 176 x 183 x 57mm and a weight of only 1230g, the K4 is easy to use on the go.
